Be it known that we,l-nnn Enn. .Tncnxnnne and RICHARD IIOGFELDT, citizens of the German Empire,- residing at Dusseldorf, in the 5 lx'ingdom oflrussiaGermany, have invented a new and Improved Machine for Coating Labels with an Adhesive, of which the following is a specification.

' By means of the machine illustrated in the accompanying drawings the labels or the like which are to be attached are individuz'rlly mated with warm glue or cold adhesive me- .un on the side where they are to be attached .nd conducted to a pair of pincers which witiulraw them from the coating mechanism.

In the accompanying drawings, Figure 1 is a side view in partial section, and Fig. 2 is an end view of the machine, while Fig. 3 is a side View opposite to Fig. 1. Fig. 4 shows a planofihe casing for the labels or the like which are to be coated with adhesive medium, and Fig. 5 is a plan of the pincers; Fig. 6-, a detail of the cam and lever for actuating the gripper; Fig. 7, a detail of thclabel-magazine and its actuating mechanism; Fig. 8, a side view of the gripper, showing the jaws open; and-Fig. 9,a similarview with the jaws closed.

A drum 1, round or angular in cross-section, serves for the reception of the'adhesive medium, delivers the same to thelabels, and passes on thelatter. This drum is moved by suitable driving gear. In the arrangement shown in the drawings aclich 2 serves to actuate the said drum, said click being influ- 35Zfenced, onthe one hand, by a spring sand, on

the other hand, by an eccentric 3, fast on shaft 38.

respondingly-toothed wheel 5, connected with a drum, and moves the said wheel with the 4o ,(lllllll intermittently. The drum can be fixed after each movement by a stopping contrivance. In theiu'rangementshowninthedraiw ings a bolt is provided for this purpose, which bolt is raised by an eccentric and en gages with notches 31 in a disk 32. The surface of the drum is furnished with glue by the gluing-rollers G, which take the glue from a tank or vessel 7. Under the drum a guide for the labels is provided, in which they lie piled up. The guiding contrivance consists of a movable guided plate 8, corresponding in The said click engages with a corshape with the labels to be stuck on, and a magazine of sheet metal, which can fall freely and which it used for sticking on quadrangw lar labels, as shown in Fig. 4, consists of four furnished at thetop with small projections,

which rest on the topmost label and prevent the light casing from slipping down over the labels and the plate 8. The said plate is raised by means of weights 11, which are c0nnecled with it by cords or the like 12, which or pulleys, so lhai' the topmost label net the drum while the lat er =tz-indsiill and adheres to the same- The drum is then moved on andthe next time it stops another label is attached next to the first, and so on. When the drum makes the forward movement, the plate 8 is loweredsomewhat, and the labels and the casing descend with it. The lowering is eilected by the click 1!), which engages with the teeth of the rack 16. The lever 14-, with the click 13, is pressed down against the action of the spring 15 by the eccentric 17 when the latter turns, the said click 13 pulling therack 10 and the plate 8 down with it. When the click 13, which is held by a spring 18,.descends, a pin 19 comes into contact with a slanting surface 2U of the said click, whereby the said click is disengaged, and the plate 8, with the labels, is raised by the weights 11 until the topmost label touches the circumference of the drum, which at that particular moment is stationary. The said label sticks to the drum owing to the adhesive medium on the latter, and when the drum moves-on the label is carried along with it. After the topmost label has been pressed against the drum the proc-v ess of lowering the plate, (to, by means of the click and rack is repeated, the said rack gradually ascending as the labels are taken up. In order that the label may be firmly pressed on the drum and thoroughly coated with adhesive medium at the cornors,aspring- .ted prcssi ng device 21 is arranged, which connection with the bent lever 22, said being moved by a tongue 23, which enl with its cross-arm; The label is taken I a gripper or pincers 24, which can be d in any way desired. In the arrangeshown in the drawings-the gripper resreciprooating movement from a cam 34-, on shaft 33, by angle-lever 26, Fig. (3. gripper is composed of a lower jaw 28, acted to slide 35, movable in a-gnide 25. ie jaw pivoted at 36 an upper jaw vaving a downwardly projecting arm To thisarm is pivotally connected a slide hich is also adapted to move inguide'flo, S and i).
